There are at least 44 prisoners of the Kremlin now, according to the human rights activists.

"For the first time since the annexation of Crimea, 12 pre-conflict prisoners were transferred to mainland Ukraine, following direct negotiations between the Ombudspersons of Ukraine and the Russian Federation. The UN Human Rights Monitoring Mission interviewed all transferred individuals, documenting gross violations of the right to physical and mental integrity they suffered in prisons in Crimea as well as in the Russian Federation, where they had been transferred in violation of international humanitarian law," the report said.

As UNIAN reported earlier, in March, the European Parliament adopted a resolution on the situation with Ukrainian prisoners, whom Russia illegally detains on its territory and in the occupied Crimea. European MPs urged Russia to immediately release the Ukrainians and appealed to the European Union with a call for new sanctions against those responsible for the persecution of Ukrainian citizens.
